New elastomeric material reduces weight and enhances automotive sealing performance
Cooper Standard’s Fortrex material combines the best attributes of EPDM (ethylene propylene diene monomer) and TPV (thermoplastic vulcanizate) materials, which are typically used in sealing, while eliminating their negative aspects, according to the company. Fortrex offers weight savings of up to 30% vs. traditional EPDM, while avoiding the compression set issues associated with TPV, resulting in improved sealing systems and reduced cabin noise. The company says it does not weather or bloom like EPDM and can be accurately color matched.
Fortrex is designed to be non-conductive and have a low carbon footprint across the entire material and production chain, less than TPV by 22% and EPDM by 53%. In addition, Fortrex is a dynamic material platform that can reportedly be modified for a vast list of applications and performance solutions within automotive and adjacent markets. Target applications include frame under glass and channel mounted glass run systems, inner and outer waist belt, and below belt extrusions.
